Soil is very important in civil engineering constructions. The poor engineering properties of the local soils may present many difficulties for construction and therefore need to improve their engineering properties. Stabilization techniques can be used to improve the properties of soil. Soil stabilization improves various engineering properties e.g. bearing capacity, compressibility, strength, and various other properties of soil. In this study the impact of Marble Dust to improve the strength of soil.The effect of varying percentage of marble dust with sisal fiber on properties of Expansive Soil.

density at optimum moisture content. The test results
indicate a reduction in the maximum dry density and
the optimum moisture content of soil due to the
addition of sisal fiber.
Objectives
The objectives of the research are outlined below:
To study the combined effect of varying
percentage of optimum quantity of Marble dust
and optimum quantity of Sisal Fiber on properties
of Soil.
Results
Modified Proctor’s Test Results for Soil MD mix with different fiber concentration and fiber.
The changes in properties are also very high and MDD value achieved is up to 1.97gm/cc
at fiber concentration of 0.50 percent.
Figure 1: MDD and OMC graph for 0.50 percent fiber and 20 percent MD mixed with B.C Soil
From the analysis of results presented in Table 5.5, it is evaluated that there is gain in change & results are
slightly lower than previous maintained. From these last outcomes, it is evaluated that rate of increment in
engineering properties of mix or combination is high, but after that properties get lowered down. Thus, outcome
is that the fiber concentration where highest result is obtained is at 0.5% Fiber + 20 % MD + Expansive soil
sample.
California Bearing Ratio (CBR) Test
The CBR Tests were executed out on clayey soil (B.C Soil), Clayey Soil treated with altered percentages of
marble dust ranges from 0 % to 20 %, then Soil- marble dust mix with altered fiber concentration 0.50 %
and then soil- marble dust -fiber mix. The tests were executed out by static compaction after four days soaking in
water

At 20 % MD .50% Fibre mix with B.C soil, CBR value of soil gets increased from 1.68 to 4.79 at OMC of
16.84 % and MDD of 1.97gm/cm3.
Combined results .50% fiber with 20 percent MD in B.C Soil
Properties 20% MD + B.C Soil + 0.50% Sisal Fiber
M.D.D. (gm/cc) 1.97
O.M.C. (%) 16.84
CBR (%) (Soaked) 6.96
Conclusion-
Based on the experimental investigation the following
conclusion is given within the limitation of the test
result.
Soaked CBR value of 20% marble dust mixed
soil raises up to 0.50% fiber content and after this
value starts decreasing.
In above study, Expansive soil was used and
favorable quantity of Marble dust and Sisal fiber
are 20% and 0.50 % respectively for achieving
maximum soaked CBR.
Future scope of work
In Further different fibers as reinforcing &
treating with other chemicals like lime bitumen &
other mixtures & also studying the changed
Physico-mechanical & chemical properties of
Expansive soil.
